Battery, battery assembly, and user equipment

摘要

A battery, a battery assembly, and a user equipment are disclosed. The battery includes a circuit board and a cell. The circuit board includes a first contact, a second contact, a third contact, a fourth contact, a battery management module, and a control switch. The first contact reports a capacity of the cell in the battery, or in the battery and a cascaded battery to an upper-level battery or an electricity load; the second contact receives and output the capacity of the cell in the cascaded battery; when the control switch is opened, the third contact is connected to the cell in the battery to charge or discharge the cell in the battery; when the control switch is closed, the fourth contact is connected to the third contact; and the battery management module triggers opening or closing of the control switch.

主权项

1. A battery comprising:
a cell; and a circuit board comprising a first contact, a second contact, a third contact, a fourth contact, a battery management module, and a control switch, wherein the first contact is connected to the battery management module and is electrically connected to an upper-level battery or is connected to an electricity load, wherein the first contact is configured to report a capacity of the cell in the battery or report the capacity of the cell in the battery and a capacity of a cell in a cascaded battery behind the battery to the upper-level battery or the electricity load, wherein the second contact is connected to the battery management module and is electrically connected to a lower-level battery, wherein the second contact is configured to receive the capacity of the cell in the cascaded battery behind the battery and output the capacity of the cell in the cascaded battery behind the battery to the battery management module, wherein the third contact is connected to the upper-level battery or the electricity load, wherein the third contact is configured to, when the control switch is opened, connect to the cell in the battery to charge or discharge the cell in the battery, wherein the fourth contact is connected to the lower-level battery and is configured to, when the control switch is closed, connect to the third contact such that the lower-level battery performs corresponding processing, wherein the battery management module is connected to the cell, the first contact, the second contact, and the control switch in the battery, and wherein the battery management module is configured to trigger, according to at least one of the capacity of the cell in the battery and the capacity of the cell in the cascaded battery behind the battery, opening or closing of the control switch.
